Hi.
I tried running it as follows :
On client
./sipp –mi 192.168.0.2 –r 1 –sn uac_pcap 192.168.0.1
On server
./sipp –I 192.168.0.1 –rtp_echo –mp 6000 –sn uas.
Now, on the server it has "Total echo RTP pckts 1st stream". However, on the client it doesn't say this. Also on the Server it doesn't say that any of the packets have been echod. The counter never increases.
So server is listening. It is ok for the client not to display the same as rtp_echo is not enabled.
This is the output from the client :
1 new calls during 0.081 s period 7 ms scheduler resolution
6 concurrent calls (limit 27) Peak was 6 calls, after 6 s
0 out-of-call msg (discarded)
1 open sockets
520 Total RTP pckts sent 62.018 last period RTP rate (kB/s)
Looks good.
The server has the following :
1 new calls during 3.659 s period 19 ms scheduler resolution
0 concurrent calls Peak was 0 calls, after 0 s
1 open sockets
0 Total echo RTP pckts 1st stream 0.000 last period RTP rate (kB/s)
0 Total echo RTP pckts 2nd stream 0.000 last period RTP rate (kB/s)
It just seems that no packets are getting echoed. Does echo need to be started on both sides, do I need to add –rtp_echo onto the client command line too?
No. Can you send the output of -trace_msg? Also can you tell from tcpdump or Wireshark where the RTP packets are sent?
I don't know if this helps, but my overall goal is to create a rtp stream/session so that I can measure the jitter on the packets, would this even be possible like this?
Yes, if you use another tool that measure the jitter: SIPp doesn't do that (yet :o)). Wireshark does it.
Olivier.
